I run a failzeroed/EXO coated ar15 bcg and trigger groups and love them--super easy to clean and self lubricating. That is the first matte finished thing I've seen from them. I wonder if it is a different coating.

the exo glock slide finishes indeed look different than fail zero's AR bcg finish. it's more of a matte finish on the glock slide, where as it's more polished and shinier on AR bcg's.
